Omron / Sentech Sentech STC-SPB203BPCL / STC-SPC203BPCL (20MP Camera Link, IMX541)

STC-SPB203BPCL

The STC-SPB203BPCL (mono) and STC-SPC203BPCL (color) are area-scan cameras with a 20.3 MP (4504 x 4504) Sony IMX541 1.1" global-shutter CMOS sensor and 2.74 µm square pixels, running at 26.0 fps over a Camera Link interface (80bit / Full / Medium / Base, Camera Link 2.1). They use a C-mount lens mount and accept either PoCL or external +12 VDC power, consuming 4.0 W or less. The compact housing measures 35 x 35 x 40.7 mm and weighs approximately 70 g, with a 0 to +40 deg. C operating range. The color model outputs Bayer RG 8/10/12-bit formats while the mono model outputs monochrome.

Technical overview

This is a 20.3 MP area-scan camera built on the Sony IMX541 1.1" Pregius S global-shutter CMOS sensor, delivering a square 4504 x 4504 frame from 2.74 µm pixels. The combination of a global shutter and a 20-megapixel format makes it a high-resolution detail tool rather than a high-speed one: every pixel is exposed simultaneously, so fast-moving or indexed parts are captured without the skew and smear a rolling shutter would introduce, while the dense pixel grid resolves fine features across a large field of view in a single capture. The square aspect ratio is unusual and genuinely useful here, because it matches the symmetry of wafers, panels, and pallet-style layouts and lets you cover a square inspection area without wasting sensor real estate or stitching multiple acquisitions.

The interface is Camera Link (Camera Link 2.1, supporting 80-bit / Full / Medium / Base configurations with PoCL), which is the defining design-in consideration. Camera Link is a deterministic, low-latency, frame-grabber-based link with no protocol overhead jitter, so this camera targets installations where a grabber already exists or where guaranteed timing matters more than cabling convenience. At full 20.3 MP it runs 26.0 fps, which is brisk for this resolution class and means the bottleneck is usually optics and lighting, not the link. Power is flexible: it accepts PoCL (power over Camera Link) to reduce cabling, or an external +12 VDC supply, and draws 4 W or less. It exposes a GenICam interface over Camera Link 2.1, so it slots into standard machine-vision software stacks for configuration and acquisition.

Optically and physically, the camera uses a C-mount and a 1.1" optical format, so you must specify a lens rated to cover a 1.1" image circle and resolve 2.74 µm pixels. Pairing it with an undersized or low-line-pair lens will throw away the resolution the sensor provides, particularly toward the corners of the square frame. The housing is compact black aluminium (35 x 35 x 40.7 mm, about 70 g), which makes it easy to mount on a gantry, robot wrist, or tight inspection cell, but the 0 to +40 deg. C operating range means it expects a controlled or moderately ventilated environment rather than a hot enclosure. The camera is offered in a mono version (STC-SPB203BPCL) and a color version (STC-SPC203BPCL); the color model outputs Bayer RG at 8/10/12-bit, while the mono model outputs monochrome and is the right choice when you want maximum effective resolution and sensitivity for geometric or surface inspection.

Best for

  • High-resolution surface and defect inspection of flat parts such as wafers, displays, and panels, where the 20.3 MP square sensor covers a large area in one global-shutter frame
  • Dimensional measurement and metrology on indexed or stepped parts, where global shutter prevents geometric distortion and the dense 2.74 µm pixel grid supports tight measurement tolerances
  • OCR/OCV and printed-mark verification on packaging and printed media, using the high pixel count to resolve small characters across a wide field
  • Traceability and 2D-code reading on electronics and semiconductor lines where a Camera Link frame grabber is already part of the architecture
  • Color print and assembly inspection using the STC-SPC203BPCL Bayer RG color variant when chromatic defects or color sorting are part of the task

Selection notes

  • This is a Camera Link camera (Camera Link 2.1, Full/Medium/Base/80-bit, PoCL) and requires a compatible frame grabber and Camera Link cabling; it is not a plug-and-play GigE/USB camera, so confirm your grabber supports the configuration and PoCL if you intend to power over the link.
  • Specify a C-mount lens that covers the 1.1" optical format and resolves 2.74 µm pixels; under-spec optics will limit usable resolution well below the 4504 x 4504 native grid, especially at the edges of the square frame.
  • Decide mono vs. color up front: the monochrome STC-SPB203BPCL gives full per-pixel detail and sensitivity for geometric and surface tasks, while the color STC-SPC203BPCL outputs Bayer RG 8/10/12-bit and trades some effective resolution for color information.
  • Plan power and thermals around the 4 W (or less) draw, +12 VDC or PoCL supply, and the 0 to +40 deg. C operating range; in a sealed or hot enclosure, ensure ventilation to stay within spec.
  • At 26.0 fps full-frame and 20.3 MP, throughput is high but exposure time and lighting drive performance; pair with strong, well-controlled (and for moving parts, strobed) illumination so you can keep exposures short enough to freeze motion without underexposing.
